,HEATING-.STOVE- SPECIFICATION forming partof Letters Patent No. 603,742, dated May 10, 1898. YApplication iiled July/30,1897. Serial No. 646,514. (No model.)

To all whom it mag/concern: v

Be it known that I, ALEREDG. RYLEY, a citizen of the United States, residing at Memphis, in the county of Shelby, State of Tennessee, have invented certain new and'useful Improvements in Heating-Stoves, of which the following is aspeciiication, reference being had therein to the accompanying drawings. J. l

This invention relates "to heating-stoves, and has for its object to provide a stove in which the products of combustion will be brought into contact with an extended radiating-surface before their final exit into the smoke-flue.

It has for a further object to improve the construction of a stove of this character by the use of a body formed of portions having plane and corrugated surfaces or two corrugated surfaces in contact with each other, so as to form smoke-dues between the same.

The invention has for a further object to improve the construction of the outlet-flue, so as to prevent the direct passage of the products of combustion from the radiatingiiues to the outlet.

Other objects and advantages of the invention will hereinafter vappear in the following description, and the novel features thereof will be particularly pointed out in the appended claims.

In the drawings, Figure 1 represents a perspective of the stove with parts broken away to show the interior construction. Fig. 2 is a horizontal section upon the line 2 2 of Fig., l, looking upward; and'Fig. 3 is a detail of a modified form of the invention.

Like letters of reference indicate like parts throughout the several figures of the drawings.

The letter A designates a stove of any suitable character, which in this instance has been illustrated as a sheet-metal stove. The stove is composed of a body portion A', provided with a cast-metal top A2 and supporting-basev bottom A2, which latter is provided with the usual legs or feet A4. The inner portion of the stoveis illustrated as composed of a plane or corrugated metal cylinder B, having a bottom B'. Extending circumferentially of this cylinder B is a corrugated cylinder C, which is secured to the plane cylinder B in any suitable manner, so that the corrugations Cof the cylinder C will form a series of flues outside of the cylinder B. The cylinder C is also provided with the usual ash-doorC2 and a door C3 for removal of waste vmaterial from the lower portion of the casing. -The corrugated cylinder is also suitably secured to the top and base sections of the stove and'v extends above and below the plane cylinder B, whereby the products of combustion will rise above the upper edge of the cylinder B and pass down the corrugations of the cylinder C to the lower "portion of the casing, whence they are forced to pass to the outlet-flue D and smoke-pipe E or other suitable conveying means.

When starting a fire, it is often desirable to provide an outlet at the top of the stove, for which purpose a iiueF is provided having therein a damper F. After the iire is started this damper is closed and the products of combustion pass downward to the flue D.

It will be observed `that l have by the use of a corrugated sheet of metal produced a stove in which a series of flues radially arranged may be used, which character of stove in the prior art has required the construction and insertion of a series of independent pipes. The corrugated cylinder is capable of being constructed by simply rolling or stamping the same from sheet metal, so that the cost of kconstruction of therstove is veryA materially reduced, while the a'dvantagesof an increased radiating-surface are fully attained.

r`I have illustrated the stove as being provided with" a grate B2 and adapted for the use of coal as a fuel by the introduction of the same at the top A2; but the grate B2 may be omitted, if desired, and wood fuel used within the plane cylinder B. It is also obvious that the arrangement of the plane and corrugated cylinders shown in Fig. 1 may be modified, so as to use two corrugated plates with the bases of the corrugations secured togetherfor instance, as shown in Fig. 3, wherein the inner cylinder B, is provided with corrugations B2, the bases B3 of which are in contact with the corrugated cylinder C.

The corrugated cylinders have been shown as formed with flattened portions B3 and C4, which are adapted to come into contact, so as to form a bearing against the adjacent cyl- IOO inder to secure the two parts together and form a circular flue. The corrugations are suitably cut away, when desired, to provide of the stove directly into the outlet-fine, the

Walls of this flue have been extended inward beneath the bottom B of the cylinder B, so

that the products of combustion from the rear` iiues would be directed toward the front of the stove before they can enter the outletlue. It is obvious that such construction will cause the products of combustion to come into contact with the base A3 of the stove, so that the same will serve as a radiating-sur-A face.

In the use of corrugated plates or surfaces the functions of a series of tubes heretofore used in a stove of this character are perform ed by a very simple construction. The heat from the fuel is retained as long as possible in contact with the surface of the stove, so as to attain an extended radiating-surface and an ornamental appearance given to the stove.

It is obvious that the principles of this invention are applicable to furnaces and other heating apparatuses by making the necessary alterations to adapt the parts to such uses.

I have described with particularity the details of construction and configuration of the several parts of this invention; but it is obvious that numerous changes may be made i in the same without departing from the'spirit of the invention.

Having described my invention and set forth its merits, what I claim, and desire to secure by Letters Patent, is

1. A heating-stove comprisinga corrugated outer cylinder closed at its opposite ends, an

inner cylinder open at its upper end and supy ported in contact with said corrugated cylinder above the lower end thereof, and an outlet-flue communicating with the space below the inner cylinder, substantially as specified.

2. A heating-stove comprising a corrugated outer cylinder closed at its opposite ends, an inner cylinder open at its upper end and supported in contact with said corrugated cylinder above the lower end thereof, and an outlet-Hue communicating With the space below the inner cylinder and provided -with vertical walls extending beneath the same, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.
